The study shows that the "golden zone" of friction produces perfect finger strokes.

The Marvel Cinematic Universe changed drastically at the end of Avengers: Infinity War with the infamous flick of Tanos. But can the intergalactic warlord ever break his fingers while wearing the cumbersome metallic Infinity Glove? This question is the inspiration for a new article published in the Royal Society Liaison Journal examining the biomechanics of finger taps, particularly the role of friction.

According to a new study, finger tapping results in the highest rotational acceleration observed in humans. According to a new study, finger tapping results in the highest rotational acceleration observed in humans.

"For the past few years, I've been fascinated by how our fingers break." "Technically, this is a puzzle of extraordinary physics at our fingertips that has not yet been carefully explored," said one of the authors, Saad Hamala, an engineer in Georgia. The power is loaded into a collective spring system and held in place by a latch. When the latch is quickly released, all the stored potential energy is released in a short time.

Many small organisms are able to make ultra-fast movements through a similar locking mechanism: frog legs and a chameleon's tongue. For example, in addition to the explosive seeds of plants, numerous types of termites, the lower jaws of ant traps. In the case of the powerful mantis shrimp punch, small structures in the muscle tendons called sclerotia act as switches. The shrimp's muscles tension the saddle-like structure of the arm, flexing it and storing potential energy that is released by swinging the paddle-like claw.

Bahmala et al. Interested in studying these movements Stunningly powerful and fast.But the current study is driven in part by watching Infinity War in 2018. In the movie, the villain Tanus collects all six Infinity Gloves, puts them into the metal Infinity Glove and kills half of their lives. You're in the world with just a tap of your fingers.But it sure is. He couldn't dispel the annoying idea that perhaps Tanos couldn't hit at all while wearing metal gloves.

This is because he thought friction played a more important role in the game's finger lock compared to other LaMSA systems. According to the authors, The muscles of the arm act as a motor that carries the potential energy to the tendons of the fingers.These, in turn, act as the springs.Pressing the middle finger and thumb together causes Create a force that trips when the middle finger slides along the thumb, causing a blow. Bamla and colleagues hypothesize that the natural friction of the skin between the middle finger and the thumb has a dual role, helping to "pinch" the middle finger and preventing it from opening. The researchers designed a series of experiments to test this hypothesis.

For the kinematic measurements, they used a high-speed camera to record a set of images of three different people. The researchers placed circles of reflective tape on the wrist joint, the base of the fingers, the first tape, the second tape, and the tip of the middle finger. For each different surface they tested, they scored five strokes: an oiled nitrile glove, latex rubber fingers on both fingers, and a metallic finger on both fingers under the nitrile glove. (The authors note that participants were allowed to rest for one minute to prevent joint and muscle fatigue.) src = "https://safirsoft.com/picsbody/2111/11918-2.jpg" alt = "https://safirsoft.com Why can't Tanos break his fingers while wearing an infinity glove? srcset = "https://cdn.arstechnica.net/wp-content/uploads/2021/11/fingersnap1.jpg 2x"> Zoom/Saad humiliates the friction-based locking mechanism by tapping with his fingers.

Researchers' measurements show that the rotational acceleration of a finger kick is approximately three times faster than that of a professional baseball field, although the rotational acceleration is slower than that of professional baseball players. “When I first saw the data, I jumped out of my seat,” Hamala said. "A fingertip occurs in just seven milliseconds, twenty times faster than an eye blink, which takes more than 150 milliseconds." A kind of cool spot or 'golden zone': just the right amount of friction and pressure to hit it hard. The sledding gloves were very slippery, there was not enough friction, so not much energy was stored. Rubber fingers produced a lot of friction, and lost as much energy as heat. Metal Fingers had the worst performance: there wasn't enough energy to create a hit.

This latest discovery has important implications for the design of Infinity War. "Our results show that Tanos could not strike because of his metal-armored fingers," said one of the article's authors, Rajav Acharya, an undergraduate student at Georgia Tech. Therefore, it is likely that Hollywood special effects, rather than real physics, will be present in the game. Sorry for the spoiler. This is bad news for Tanus, but these findings will likely help improve the synthetic design and frictional dynamics of future soft robots.
